Thanks for the advice guys - I never thought of that (obviously
). I checked the camera and the seals are in fact dry and flaky. There is also a rough edge on the lower part of the door itself, probably from the moisture that was held in the original seal. I'll order a seal kit from US Camera ($7.65 on ebay) and hopefully all will be good.
My son is really loving analog photography and darkroom work. When he went back to school this weekend he asked if he could bring my SRT-202 with him. I offered him my XD11 and he said - no thanks, I prefer the manual meter over the autoexposure. Good kid
